摘要

FIELD: agricultural engineering. ^ SUBSTANCE: thresher has threshing cylinder with deck and stripper beater including separating screen. Straw shaker is positioned rearward of stripper beater. Shaking stand is hung on suspensions under threshing cylinder deck. Additional threshing device is positioned rearward of front shaking stand screen and is composed of upper and lower rolls. Length of rolls is equal to width of threshing and separating device. Lower roll of additional threshing device is arranged above main fan diffuser. Additional fan diffuser directs air flow onto shaking stand screen. Thresher of such construction provides for additional ear threshing and separation of grain before grain heap is delivered to main cleaning device. ^ EFFECT: increased efficiency of thresher and reduced grain losses. ^ 3 cl, 2 dwg
